The nematode Caenorhabditis elegans has allowed scientists to develop "fate maps" tracing cell lines back to cell origins. The trait of nematodes and some other related groups where they have a set number of cell divisions leading to the same number of body cells in an adult is called:
A) anisogamy.
B) apoptosis.
C) cryptobiosis.
D) gastrulation.
E) eutely.
Answer:
The correct answer is E) eutely
Explanation:
Nematodes are organisms with bilateral symmetry, although their organs are coiled, sometimes one of the limbs is lost and many of sedentary life tend to radial symmetry. One of the most striking characteristics of these animals is that their growth is not produced by an increase in the number of cells that compose them, but by an increase in the size of the already existing cells; in fact, in most adult tissues the number of cells is constant, a phenomenon known as eutelia.
Eutelia is the condition of an organism composed of a constant number of cells or syncytial nuclei in all adult individuals of a species, such as nematodes, it means that body growth is not carried out by increasing the number of cells but by the growth of existing cells.
Answer:
E. Eutely
Explanation:
Nematodes is also called Nemathelminthes. They are small slender worms and the head of a nematode is noticeable when compared to other parts of their body. The head is radially symmetrical while the body is bilaterally symmetrical.
Eutely is however the condition of having a body made up of a constant number of cells usually somatic cells like in the case of certain rotifers and lower worms.
How many sex chromosomes does a human diploid cell contain?
Answer:
. A human diploid cell has 46 chromosomes in 23 pairs.Which situation is most likely to involve the action of a pheromone?
a. Albatrosses showing courtship behavior
b. A prairie dog emitting a loud yelp
c. The chirping of a cricket
d. Urine of a male mouse attracting a female
e. A male collared lizard showing his large mouth
Answer:
D. Urine of a male mouse attracting a female
Explanation:
Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to impact the behavior of the receiving individuals. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology.
Bees, wasps, ants, moths and other insects rely largely upon pheromones as a means of communication. Pheromones are chemical substances which may be secreted in urine, dung or produced by special glands.
Pheromones mediate many of the complex interplays within colonies of social insects such as bees, wasps, and ants.
Pheromones are chemical signals that have evolved for communication between members of the same species. A pheromone signal elicits a specific reaction in the receiver, for example, a stereotyped behavior (releaser effect) or a developmental process (primer effect). Some pheromones can have both effects. All sorts of molecules, large and small, have been found acting as pheromones, depending on whether the message is sent out on wind or water currents or placed directly on the nose or antenna of the recipient.
Most pheromones are detected by the sense of smell. However, not all smells are pheromones. Mammals, including humans, also give off a cloud of molecules that represent our unique individual "smell" or chemical profile. These differences between individuals make it possible for dogs to distinguish people by smell. People are quite good at it, too—parents can distinguish their baby from others by smell alone. Ants similarly can distinguish between members of their own colony and those from other colonies. In both mammals and insects, learning is necessary to develop this ability. The sources of the molecules that make up an animal’s "individual smell" include its own secretions and also may reflect its environment, food, bacteria, immune system, and molecules picked up from other individuals in its social group

The fur color in a colony of mice has been brown for many generations. One gene appears to code for the fur color pigment. In a recent litter of mouse pups, one mouse was born with white fur. Which of the following could have caused this change in fur color?
A. a mutation in the DNA sequence of the gene for brown fur
B. recombination between genes for fur color
C. All of these choices are correct
Answer:
A mutation in the DNA sequence of the gene for brown fur
Explanation:
The mutations are capable of changing the encoded protein product, in this case the gene that encodes for the fur color pigment. This mutation may have occurred during mitosis or meiosis divisions.
If it is a spontaneous mutation that occurred in the germinal line (meiosis) and confers an adaptive advantage, it will increase their frequency in the population.
Answer: A would be the answer. "A mutation in the DNA sequence of the gene or brown fur".

In a line of human cells grown in culture, a geneticist isolates a temperature-sensitive mutation at a locus that encodes an acetyltransferase enzyme; at temperatures above 38°C, the mutant cells produce a nonfunctional form of the enzyme. What would be the most likely effect of this mutation if the cells were grown at 40°C?
Answer:
A general decrease in transcriptional activation
Explanation:
When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to 40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.
Answer:
A general decrease in transcriptional activation
What would you not find in the cerebral cortex?
Answer:
Fiber tracts are not found in cerebral cortex.
Explanation:
The Cerebral Cortex is made up of tightly packed neurons and is the outermost layer of the brain.The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. There are billions of neurons in the cortex which are organized in cortical columns, and minicolumns of the layers of the cortex. There are six cortical layers of the neocortex each contain a characteristic distribution of different neurons and their connections with other cortical and subcortical regions.
The cerebral cortex is responsible for many higher-order brain functions such as sensation, perception, memory, association, thought, and voluntary physical action. The cerebrum is the large, main part of the brain and serves as the thought and control center. It is also responsible for higher thought processes including speech and decision making .
The cortex is divided into four different lobes, the frontal, parietal, temporal, and occipital, which are each responsible for processing different types of sensory information.

In cocker spaniels, black color (b) is dominant over red (b), and solid color (S) is dominant over spotted (s).
If the genes are linked and the offspring of BBss and bbss individuals are mated with each other, what fraction of their offspring will be black and spotted?
a) 1/16 b) 9/16 c) 1/9 d) 3/16 e) 3/4
Answer:
e) 3/4Explanation:
As given;
Black (B) is dominant over red (b), so B is dominant over b.
Solid (S) is dominant over spotted color(s), so S is dominant over s.
Offspring of BBss and bbss individuals are:
Gametes of parent BBss are Bs, Bs and gamete of bbss are bs, bs
offspring are : all Bbss
Cross between these offspring is; Bbss×Bbss
Gametes of parent Bbss are: Bs and bs as given that the genes are linked.
Bs, bs × Bb, bs
Offspring are = BBss, Bbss, Bbss, bbss
Black spotted (B_ss) = 3/4
The correct answer is d) 3/16. The fraction of offspring that will be black and spotted is 3/16.
To solve this problem, we need to consider the genotypes of the offspring produced by the mating of two heterozygous individuals for both traits (black/red and solid/spotted). The parents are both heterozygous for both traits, so their genotypes are BbSs.
Let's first determine the possible gametes that each parent can produce through meiosis. Each parent can produce four types of gametes: BS, Bs, bS, and bs, with each gamete having an equal probability of 1/4.
Now, we will use a Punnett square to determine the genotypic probabilities of the offspring. The possible combinations of gametes are as follows:
- BS x BS: BBSS (black, solid)
- BS x Bs: BBSs (black, solid/spotted)
- BS x bS: BbSS (black/red, solid)
- BS x bs: BbSs (black/red, solid/spotted)
- Bs x BS: BBSs (black, solid/spotted)
- Bs x Bs: BBss (black, spotted)
- Bs x bS: BbSs (black/red, solid/spotted)
- Bs x bs: Bbss (black/red, spotted)
- bS x BS: BbSS (black/red, solid)
- bS x Bs: BbSs (black/red, solid/spotted)
- bS x bS: bbSS (red, solid)
- bS x bs: bbSs (red, solid/spotted)
- bs x BS: BbSs (black/red, solid/spotted)
- bs x Bs: BbSs (black/red, solid/spotted)
- bs x bS: bbSs (red, solid/spotted)
- bs x bs: bbss (red, spotted)
We are interested in the offspring that are black and spotted, which corresponds to the genotype BbSs. From the combinations above, we can see that there are three combinations that result in BbSs:
- BS x bs: BbSs
- Bs x bS: BbSs
- bs x Bs: BbSs
Each of these combinations has a probability of 1/4 (for each gamete) times 1/4 (for the other gamete), which equals 1/16. Since there are three such combinations, we multiply the probability by 3:
3 * (1/4 * 1/4) = 3 * 1/16 = 3/16
How do metal atoms bond with one another?
Answer:
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. ... Metals are shiny.
Explanation:
i took it from google
Answer:
Metallic bonds are mediated by strong attractive forces. This property contributes to the low volatility, high melting and boiling points, and high density of most metals. The group-XII metals zinc, cadmium, and mercury are exceptions to this rule.
Explanation:
Metallic bonds can occur between different elements, forming an alloy. Aluminum foil and copper wire are examples of metallic bonding in action .
Metals make up most of the elements in the periodic table (around 80%), and they are special. When metals bond with themselves, they bond in a different way than when they bond with other elements. It isn't ionic or molecular or covalent. It is its own metal bond.
When metals are together, the electrons float around the atoms; they roam around the whole metal complex. They float free as though floating through a sea of electrons, much like an individual water molecule floats free in the sea. This is why it is called the electron sea model.
Each metal atom allows its electrons to roam freely, so these atoms become positively charged cations. These cations are kind of like a positively charged island and are surrounded by a sea of negatively charged electrons. It looks a bit like positively charged cations surrounded by electrons .
Most metals have very few electrons in their outermost energy shells, and some have vacant outer electron orbitals. What this means for the metal is that its valence electrons are decentralized and free to move around. Remember that in ionic bonds, the electrons transfer from one atom to another atom. In covalent bonds, the electrons are shared between atoms. In metal bonds, the electrons wander around and aren't transferred or shared. It's more of a communal thing where they belong to all the metal atoms around them.
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.

A protein that spans the phospholipid bilayer one or more times is
Answer:
a transmembrane protein
Explanation:
A transmembrane protein spans the phospholipid bilayer one or more times. they are made of amphiphilic phospholipids: phospholipids with a hydrophilic phosphate head and a hydrophobic tail with two fatty acid chains.
A protein that spans the phospholipid bilayer one or more times is called an integral protein. These proteins are incorporated into the membrane structure, with hydrophobic and hydrophilic regions that allow them to align with the hydrophobic region and interact with the hydrophilic regions of the phospholipid bilayer.
Explanation:A protein that spans the phospholipid bilayer one or more times is an integral protein. These proteins are integrated into the membrane structure, consequently, their hydrophobic membrane-spanning regions are able to interact with the phospholipid bilayer's hydrophobic region. Depending on their structure, some integral proteins span only part of the membrane associating with a single layer, while others stretch from one side of the membrane to the other, being exposed on either side. Moreover, these proteins can be additionally described based on their hydrophilic and hydrophobic regions, enabling them to align alongside the phospholipids, with the protein's hydrophobic region adjacent to the tails of the phospholipids and the hydrophilic region in contact with the extracellular fluid or cytosol.

Answer:
The plant produces seeds that are enclosed in fruits.
Explanation:
One possible observation that can make a scientist to effectively conclude that an unknown plant is an angiosperm is the possession of seeds which are enclosed in fruits.
Only gymnosperms and angiosperms produce seeds but while gymnosperms's seeds are bore in the form of naked cones, angiosperm's seeds are are enclosed in a fruit.
Every other group of plants that do not produce seeds belongs to one of ferns, bryophytes or algae.
An individual sustained a closed head injury in a rock climbing accident. In the ER the RN elevates the head of the bed at 30 degrees and keeps his head in a straight position. What is the physiologic rationale for the positioning?
Answer:
Answered below
Explanation:
Head injuries may be penetrating head injury or closed head injury.
A major concern for health professionals regarding intracranial injuries resulting from closed head traumas, is the management of intracranial pressure. Elevated intracranial pressure have negative effects on the brain and immediate management of raised intracranial pressure is important to avoid cerebral edema, intracranial hematoma, brain herniation and even death.
The usual procedures in the management of head injury include elevating the head to about 30 degrees. This position promotes cerebral venous drainage and decreases intracranial venous pressure and intracranial pressure as well.
This is helpful because when the patient is left in the horizontal position, the intracranial pressure becomes significantly higher and the have fatal consequences.

Dr. Graham exposes rats to a vanilla scent prior to receiving a food pellet in the left corner of their cage, but provides no food after exposure to a lemon scent. After several trials, upon smelling a vanilla scent, the rats wait at the far left corner of the cage regardless of whether a food pellet is present. However, they do not wait in the far left corner when exposed to the lemon scent. What is the unconditioned stimulus in the experiment?
a. food pellet
b. vanilla scent
c. lemon scent
d. left corner of cage
Answer:
a. food pellet
Explanation:
In classical conditioning, an unconditioned stimulus is the stimulus that naturally elicits an unconditioned response. The unconditioned stimulus is usually paired with a neutral stimulus, and after pairing with a neutral stimulus, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response alone.
In the experiment described above in the question, the unconditioned stimulus is the food pellet, which naturally elicits the response of the rat to wait at the far left corner of the cage. The neutral stimulus which is paired with the food pellet is the vanilla scent, which now becomes the conditioned response, when paired alone.

Mendel's law of independent assortment has its basis in which of the following events of meiosis I?
alignment of pairs of homologous chromosomes along the middle of the cell
synapsis of homologous chromosomes
crossing over of homologous pairs of chromosomes
the division of cells at telophase
Explanation:
Alignment of pairs of homologous Mendel's law of independent assortment, expresses that allele sets separate during the arrangement of gametesThis implies qualities are transmitted to offspring independently of one anotherDevelopment of random combinations of chromosomes in meiosis and of qualities on various sets of homologous chromosomes by the entry as indicated by the laws of probability of one of every diploid pair of homologous chromosomes into every gamete independently of one another pairMendel's law of independent assortment has its basis in the alignment of pairs of homologous chromosomes along the middle of the cell.
WHAT IS MENDEL'S LAW OF INDEPENDENT ASSORTMENT:Mendel's law of assortment states that alleles of a gene segregates independently into gametes. According to Mendel, the segregation of alleles into gametes does not interfere the segregation of another. The alignment of homologous chromosomes during the metaphase stage of meiosis 1 ensures that alleles segregate independently.Therefore, Mendel's law of independent assortment has its basis in the alignment of pairs of homologous chromosomes along the middle of the cell.

What could be the consequence of a mutation that changes the sequence of nucleotides in a promoter?
Answer:
The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.
When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.
